• 論文の詳細を見る

• This paper presents a new design for a traveling wave ultrasonic motor with a bolt-clamped Langevin transducer. A flexural composite transducer was attached to a ring around its circumference to excite two degenerate flexural vibration modes spatially and temporally orthogonal to each other in the ring for flexural traveling wave excitation. The prototype motor, composed of a 30-mm-diameter composite transducer attached along the outer edge of a 130-mm-diameter ring, was designed and tested. A maximum torque of 1.28 N$\cdot$m with a maximum efficiency of 3.8% was achieved when driven at an applied voltage of approximately 200 Vrms and a preload of 172 N.
